Axel Lin ddb2c42b67 mtd: brcmnand: Fix misuse of IS_ENABLED
While IS_ENABLED() is perfectly fine for CONFIG_* symbols, it is not
for other symbols such as __BIG_ENDIAN that is provided directly by
the compiler.

Switch to use CONFIG_CPU_BIG_ENDIAN instead of __BIG_ENDIAN.

Hauke Mehrtens bcb83a19d3 mtd: brcmnand: do not make local variable static
Remove static in front of ctrl. This variable should not be shared
between different instances of brcmnand_probe(), it should be local to
this function and stored on the stack.

The caller already adds a new line and in the other cases there is no
new line added.

Brian Norris c26211d37f mtd: brcmnand: add extra SoC support to library
There are a few small hooks required for chips like BCM63138 and the
iProc family. Let's introduce those now.

Brian Norris 303b4420ff mtd: brcmnand: add support for STB chips
BCM7xxx chips are supported entirely by the library code, since they use
generic irqchip interfaces and don't need any extra SoC-specific
configuration.

Brian Norris 27c5b17cd1 mtd: nand: add NAND driver "library" for Broadcom STB NAND controller
This core originated in Set-Top Box chips (BCM7xxx) but is used in a
variety of other Broadcom chips, including some BCM63xxx, BCM33xx, and
iProc/Cygnus. It's been used only on ARM and MIPS SoCs, so restrict it
to those architectures.

There are multiple revisions of this core throughout the years, and
almost every version broke register compatibility in some small way, but
with some effort, this driver is able to support v4.0, v5.0, v6.x, v7.0,
and v7.1. It's been tested on v5.0, v6.0, v6.1, v7.0, and v7.1 recently,
so there hopefully are no more lurking inconsistencies.

This patch adds just some library support, on which platform drivers can
be built.
